At the same time, the boss arranged on the outside can strengthen the fixation of the barbs arranged on the inside.

[0013] The utility model is further configured that the control box bottom protective cover structure includes a control box bottom ventilation protective cover, the control box bottom ventilation protective cover is symmetrically provided with ventilation holes, and the remaining structure of the control box bottom ventilation protective cover is the same as the structure of the control box bottom sealing protective cover.

[0014] Through the above technical scheme, two flexible pin holes are added to the bottom shield of the control box during mold design, and the sealing shield at the bottom of the control box or the ventilation shield at the bottom of the control box can be selected for processing and molding as needed. When the controller needs to be completely sealed, a sealing shield at the bottom of the control box without ventilation holes is used. When the controller needs to go to a plateau and a circuit board is required to detect the oxygen content of the plateau, a ventilation shield at the bottom of the control box with two ventilation holes is used, so that the controller can monitor the altitude of the product in real time and issue corresponding instructions to make the ratio of air and fuel reach an ideal state, so that the heater can fully burn the fuel.

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model has a compact structure design, diverse functions, small size, good sealing, and is relatively convenient to install and use.
